Screened window



May 18, 1937. K. H. FEIGE SCREENED WINDOW Filedl Aug. 14, 1935 Patented May 18, 1937 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to window screens of the roller type. Among the salient objects of the invention are to provide a construction which may be readily applied to existing windows with a minimum of alterations; to produce a construction which may be incorporated in either metal or wood sash; to render possible the use of an ample length of screen fabric; to devise a construction which shall not interfere with the proper closing of the window; to provide means for holding the edges of the screen against a suitable surface to prevent flies from passing around the edges; and in general to provide a neat,

simple, inexpensive and efiicient screened window.

In the accompanying drawing:

Figure 1 is a perspective view of a screened window embodying the features of my invention, the view being taken from within the room.

Fig. 2 is a fragmental vertical sectional view through the window frame, the lower sash and the screen, the lower sash being shown in raised position, as in Fig. 1.

Fig. 6 is a fragmental perspective View showing a yielding mounting for the screen roller.

Fig. 7 is a fragmental perspective View of the lower left-hand corner of thel lower sash, as viewed from within the room.

In the drawing, I denotes the window frame, the window sill or ledge being indicated at 2. The upper sash is not shown in the drawing, but it is intended to be adjustable up and down, ir 40 desired, along the vertical stops or guides 3 (Figs. Zand 4). In Fig. 2 the path of movement of the upper sash is at the right of the stop 3.

The lower sash is herein shown as an ordinary wooden sash with the lower rail replaced with a rail embodying features of my invention. The sash comprises the usual wooden stiles I and upper rail 5 (Figs. l, 3 and 7). The lower rail 6 (Fig. 7) is formed' of sheet metal and takes the place of the usual wooden lower rail of the lower sash. The sheet-metal lower rail 6 is formed of sheet metal bent to provide a front wall l, a rear or outer wall 8 and an upper edge wall 9, sai-d edge wall being bent to form a seat I6 for the `lower edge of the window pane II. The bottom wall I2 of the rail 6 is formed of a separate piece of sheet metal bent to lit snugly between the wallsy 1 and 8. The bottom wall I2 has an upstanding flange I2.a at the sides and ends (see Figures 2 G9 and 6) and is removably secured in place in any preferred way, as, for example, by friction. The ends i3 of the lower rail 6 are formed from sheet metal (Figs. 4, 6 and '7).

In the ordinary woo-d sash the rails lie between the stiles. In applying my invention to such a sash, the lower rail is removed, the stiles shortened by sawing off the lower ends thereof, and slots I5 (Fig. 3) formed in the shortened ends of the stiles.

The end portions of secured to the vlower the metal rail 6 are then ends of the wooden stiles Il by means including an upwardly extending web or flange I4 formed on each end of the rail 6, said flanges extending into the slots I5 (Fig. 3) in the lower ends of the stiles 4 and being secured in place. by means of screws I6 (Figs. 1, 3 and 7) extending into the stiles and through said anges.

Within the hollow rail 6 is rotatably mounted a spring-actuated roller upon which is wound a sheet of wire cloth, textile fabric or other desired flexible material, the outer lower edge of said fabric being detachably secured to thel window frame at the window sill. The roller is indicated at I T in Figs. 4 and 7. It consists of a tube having plugs I8 in its opposite ends, said plugs being rotatably mounted upon a pivot rod I9. The ends of the pivot rod are flattened to extend nonrotatably through vertical slots 2li in the end walls I3 of the rail 6. The roller is yieldingly supported within the rail 6 by means ofy twoI springs 2|, ene under each end of the pivot rod i 5, a block 22 slidably mounted in the slot 2E] being interposed between the spring and the pivot rod and being connected to the spring. The lower end of the spring 2| is secured in notches formed in the walls of the slot 26, as shown in Fig. 6. It will be understood that the spring mounting of the roller will allow the roller to yield in case of a sudden or violent upward tug on the sash, and will also permit the ends of the roller to adjust themselves in the screen under even tension.

A torsion spring 23 (Fig. 4) is secured at one end to the pivot rod I9 and at its opposite end to one of the plugs I8, said spring tending to revolve the roller Il in the direction to roll up the beforementioned sheet of screen fabric. Said sheet is indicated at 24. Its upper end is attached to the roller Il. The bottom wall I2 of the rail 6 has a slot 25 therein to allow the screen 24 to extend therethrough. As herein shown, the lower edge of the screen 24 is secured to a rod 26 (Fig. 5), end-section 2l. rI'he ends of the rod 26 project beyond the vertical edges of the screen 24 into position to be engaged by the notched lower ends of two leaf springs 23 secured at their upper ends to the window frame I. It will be seen that by contracting the rod 26 and sliding it with referheight so as to hold said rod comprising a spring-pressedl ence to the screen 24 and by forcing the lower ends of the leaf springs 28 apart, the screen may be freed from its connection with the window frame, whereupon the spring 23 will act to roll up the screen and hold the lower end thereof within a recess 29 formed in the lower side of the bottom wall |2 of the rail 6.

If it should be desirable to remove the roller 1 from the window, the lower wall I2 may be removed, the springs 2| disengaged from the walls of the slot 20, and said springs,.the blocks 22 and the pivot rod I9, with the roller thereon, removed from the rail 6.

Means is provided to hold the edge portions of the screen 24 in contact with the stop 3. Herein I have shown devices secured to opposite sides of the window frame which are duplicate, except that one is made right-hand and the other lefthand. 'Ihese devices include a sheet-metal casing or tube 30 which is rectangularin cross-section and which is secured to the inner side of the window frame, said casing constituting a window stop that takes the place of the usual stop located at the inner side of the path of movement of the lower sash. A suitable number of spring arms 3| are secured at one end within the tubular stop 30, and project through vertical openings 32 (Figs. 2 and 3) in the edge of the stop 30 which is adjacent to the path of movement of the lower sash. The free ends of one or more of the spring arms 3| bear against the vertical edge portions of the screen 24 whenthe lower sash is raised. When the lower sash is closed, it deiiects the free ends of the spring arms 3| forwardly out of its path.

If desired, means may be provided for manually operating the spring arms 3| into and out of their operative position. Herein I have shown a rod 33 having lugs 34 (Figs. 3 and 4) that project into loops 35 on the spring arms 3|. The rod 33 extends vertically within the tubular stop 3|) and its upper end is bent, as shown in Fig. 3, to extend into a slot 36 in the tubular stop. The upper and lower ends of the slot 36 extend at an angle so that when the bent upper end of the -rod 33 is placed therein therrod will be held in either its upper or its lower position, as the case may be. To the upper bent end of the rod 33 is secured a handle 31.

Means may be provided for latching the lower sash in raised position in various elevations. Herein I have shown a series of openings 38 in the Wall of the tubular slot 30 adjacent to the lower sash, each the angular end 39 of a leaf spring 40 which is secured to the front wall 1 of the rail 6 at 4|. 42 is a stud secured to the spring latch 40, said stud projecting from the wall adjacent to one of the handles 43 secured to the rail 6 of the lower sash, so that when the operator desires to'move the sash up or down the thumb of the hand that engages the handle 43 may be used to depress the pin 42 to disengage the angular end of the leaf spring 4|! from the opening 38 with which it may be engaged. I

It will be seen that I have provided very simple means whereby a window screen of the roller type may be readily applied to an ordinary window, the metal rail 6 being substituted for the 'wood rail of a wooden sash, and the tubular metal stops 30 with their appurtenances being substituted for the usual wooden stops at the inner side of the lower sash.

'I'he metal rail 6, with the attaching portions of which is adapted to receive- I4, the roller 1, its self-adjusting bearings 22, the screen 24 and the rod 26-21, constitutes a replacement unit which may be readily substituted for the rail of an ordinary sash.

The invention is notv limited to use with wooden sash, since obviously the rail 6 may be incorporated in a metal sash.

It has been proposed to apply a window screen of the roller type by attaching a casing containing such a screen to the lower edge of the usual lower rail of the lower sash, but such an arrangement is impracticable, since it prevents the lower sash from being completely closed, a gap remaining between the upper portion of the lower sash and the lower portion of the upper sash.

It has also been suggested that a screen roller be housed within the wooden rail of a sash, but such a construction is not practical, because the wood rail cannot be hollowed out sufficiently to provide a chamber wide enough to contain the roller and an adequate length of screen fabric wrapped around it.

Although VI have shown the invention as embodied in a window having a screen below the lower sash, it will be apparent that the same principle may be utilized in screening the space above the upper sash, when the latter is lowered.

For the Vsake of brevity, the word screen is used in the following claims to denote a sheet of fabric serving the purpose of a screen or filter.

I claim as my invention:

l. In a window having a vertically movable sas a roller carried by the sash, and a screen attached at one end to said roller and at its other end to the frame; a series of spring arms mounted on the frame along the path of movement of the sash to press against a vertical edge of the screen when the sash is moved to extend the screen, and manually-operable means for displacing said arms out of the path of the sash.

2. In a window, a screen, a series of spring arms located on the frame of the window and arranged to bear at their free ends against the screen, and means for moving said arms away from the screen, said means comprising a rod connected to said arms, a handle on said rod, and means on the frame to hold said rod in a plurality of positions.

3. A tubular window stop formed of sheet metal and having an opening in its inner edge, and a spring arm attached at one end to said stop and projecting through said opening.

4. In combination, a Window sash, and means for rotatably mounting a spring screen roller in the sash, said means comprising springs yieldingly supporting the ends of the roller for independent adjustment under the tension of the screen.

5. A unit comprising a sash rail having members at its ends for attachment to Stiles, said rail being adapted to house a spring roll screen, and having a one-piece which is slottedto allow said screen to pass therethrough, said screen having a rod on the free end thereof, said wall recess to house said rod, said wall being frictionally secured in place in the rail.

6. A unit comprising a sash rail having a roller screen housed therein, said rail having in its ends vertical slots, said roller screen having pivots extending into said slots, and means for yieldingly supporting said pivots in said slots.
